(54) SOFT PLASMA POLYMERIZATION PROCESS FOR A MECHANICALLY DURABLE SUPERHYDROPHOBIC NANOSTRUCTURED COATING


(57) A method for depositing a coating on a substrate is disclosed. A first precursor comprising fluoro-acrylate monomers, fluoro-alkyl acrylate monomers, fluoromethacrylate monomers, fluoro-alkyl methacrylate monomers, fluoro-silane monomers, or a combination or derivates thereof is provided. A second precursor comprising linear siloxanes, silane monomers, cyclosiloxanes, cyclosilane monomers, or a combination or derivates thereof is provided. The first and second precursors are co-injected in a treatment region. An atmospheric or reduced pressure plasma discharge is created in said treatment region. The substrate coating comprises alternated multi-stacked nanostructures and is formed by copolymerization of the first and second precursors.
